"Today, innocent children and educators lost their lives in an unspeakable tragedy. When we send our children to school, we expect they will be safe and secure. Nothing is worse than when our confidence is shaken and the safety of a child is put into question. Our hearts go out to the Newtown community as they begin the long process of healing in the days, weeks and months to come," Cassellius said.

She offered her deepest condolences to those in Connecticut.

"My heart goes out to them as they deal with this difficult situation in the coming days, weeks and months. I ask you to keep them in your prayers," she said.

She asked administrators across the school districts in Minnesota to use this time to take another good look at the safety protocols that have been developed in the districts and ensure that all staff and volunteers understand the practices and procedures needed in an emergency situation.

"It is without a doubt that moments like this bring fear and questions," Cassellius said. "Whether it's questions from students about whether their school is safe, questions from parents and the community about a school's safety protocols and questions from staff about their role in an emergency situation. It is important that everyone feels comfortable and safe and ready to handle any potential crisis," Cassellius added.
